' MOTOR-CYCLE.

SPECIFICATION forming part of Letters Patent No. 746,652, dated December 15, 1903,. Application filed May 21, 1903. fierial No. 158.124. on model.)

' ments Relating to Motor-Oars,'(for which we have filed an application in Great Britain, No.

-4,4=18, bearing date February 25, 1903,) of

which the following is a specification.

' This invention relating to motorcycles comprises the combination, with compactly-arranged worm-gearing transmitting the power of the motor, of variable-speed mechanism adapted for efiecting the quick movement of the motor for starting purposes, with a pedal movement slow enough to permit of the pir0- pulsion of the complete machine Without lin due effort by the rider.

explanatory drawings, Figure 1 is a diagrammatic view illustrating the disposition of the motor and driving-gear in relation to the cy ole-frame on which they are mounted. Fig. 2 is a sectional side elevation showing the wormgear and the speed gear or mechanism arranged in connection with the same for the purpose aforesaid. Fig. 3 is an end View of the connected casings for the said worm-gearing and speed mechanism. Figs. 4., 5, and -6 are sectional end views on the lines Z Z, Y'Y, and X X, Fig. 2, respectively. Fig. 7 is a plan of the parts shown at Fig. 2.

The same reference-letters in the different views indicate the same parts.

Theoil or other motor A is suspended from the framing of the machine, preferably in a position such as illustrated at Fig. 1, the center line of the motor crank-shaft being coincident with the longitudinal center line of the said framing, thus giving a direct driveline between the motor and the worm-gear. The crank and fly-wheel casing part A of the said motor has secured to it one end of the speed-gear casing B. The other end of the said casing is secured to the two-part casing O, containing the worm-gear comprised by the worm D and the worm-wheel E. The speedgear and Worm-gear are effectually inclosed and protected by their casings against dust .and dirt.

The connection of the three casings A, B, and C is preferably efiected by screwed bolts, as b.

The two-part casing O of the worm-gear is clamped or mounted between a pair of boss- :iike brackets forming part of the chain stay FF. the worm-wheel E are provided in the said The bearings both for the worm D and casing O, as illustrated, and in rigid connection'with the worm-wheel E is the chain-Wheel G for transmitting the power to the corresponding chain-wheel H,'Wl1l0hlS in connection with the rear road-wheel J of the complete machine. The connection between the worm-wheel E and the pedal crank-shaft or spindle Kis effected through an automatic or free wheel-clutch of-any well-known type, such as illustrated.

The portion L of the motor crank-shaft on which the combined crank and fly-Wheel disk Referring to the two accompanying sheets of part M is fixed is connected by a hollow sleeve part N with the enlarged hollow end 0 of the worm-spindle through the medium of wedgekeys, as P, arranged upon or within the said hollow end 0 and operated by the conical surfacep of a sliding plug P, arranged in the center of 0. On causing the plug P to slide, which is accomplished by means of a rocking shaft P fitted with anoperating-lever or like part, as P and a fork P transmitting the movement of the shaft P to the sleeve or collar P to which the plug .P is attached, the wedges P, acting upon the split or segmental grip-ring Q, eifect the connection or disconnection of the said sleeve part N with the said end 0 of the worm-Wheel shaft or spindle. When the parts are in connection, the motor crank-shaft and the Worm-shaft rotate as one piece, as is required for the driving of the machine by the motor in the ordinary way; but for starting purposes the grip-ring Q on the hollow end 0 of the worm-shaft. By means of the conical surface 10 of the sliding plug P, operating the wedge-keys P, the said wheel can be connected or disconnected with the said end 0. It is placed in connection by means of the lever P aforesaid, and the rotation of the worm-wheel by pedaling is then transmitted to the motor through the aforesaid gear-wheels, which are so proportioned as to cause the motor crank-shaft to rotate at a higher speed to facilitate the starting of the motor.

After the motor has itself commenced to drive the vehicle the aforesaid speed-gear can, if desired, be thrown out of action, so that the worm shall be driven directly from and at the same rate as the motor crank-shaft. At any time, however, the gear can be put into action for hill-climbing or for slow running of the vehicle.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In motor-cycles, the combination with the motor crank-shaft of worm-gearing having a chain driving-wheel in permanent connection and pedal-cranks in automatic clutch connection therewith, speed-gear, and duplicate clutches respectively and detachably connecting the said crank-shaft and worm directly and through the said speed-gear, substantially as set forth.

2. In motor-cycles, the combination with the motor crank-shaft, of worm-gearing having a driving-wheel in permanent connection and pedal-cranks in automatic clutch connection therewith, speed-gear, duplicate clutches respectively connecting the said crank-shaft directly and through the said speed-gear, cases respectively inclosing the said worm and speed gears, and clampingbolts securing the said cases to each other and to the motor, substantially as set forth.

3. In motor-cycles with worm-gearing, having a chain driving-wheel in permanent connection and pedal-cranks in automatic clutch connection therewith, the combination consisting of a gear-wheel R integral or in permanent connection with the motor crankshaft, a gear-wheel R. carried loosely upon the worm-shaft, connected wheels R and R respectively engaging the said wheels R and R and duplicate clutches respectively and detachably connecting the said worm-shaft with the said wheels R and R substantially as set forth.

4. In motor-cycles with worm-gearing having a chain driving-wheel in permanent connection and pedal-cranks in automatic clutch connection therewith, the combination consisting of a gear-wheel Rintegral orin permanent connection with the motor crank-shaft, a gear-wheelR carried loosely upon the wormshaft,connected wheels R and R respectively engaging the said wheels R and R duplicate clutches respectively and detachably connecting the said worm-shaft with the said Wheels R and R and means for the operation of the said clutches consisting of wedge-keys a double-coned plug and a rocking lever with connected fork and sliding sleeve, substantially as set forth.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
